COMBINED GRAIN HARVESTING AATD THRASHING MACHINE. v I

Application filed February 1, 1921.

"in Combined Grain Harvesting and Thrashing Machines, of which the following is a. specification.

My present invention pertains to combined grain harvesting and thrashing machines such as are designed to be moved over a grain bearing area and while in motion to out standing grain and thi'esh the same.

The object of my invention is to provide a machine of the kind stated that is simple and compact in construction, efiicient in operation, and susceptible of being easily and nicely adjusted to adapt the machine to the heights of the grain to be cut and threshed.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof:-

Figure 1 is a plan view, partly broken away, illustrating the combined harvesting and thrashing machine of m invention and also illustrating a wagon b0 y positioned to receive grain from the machine.

Figure 2 is a rear end elevation of the machine.

Figure 3 is a front end elevation of the machine.

Figure 4 is a view showing the machine in side elevation.

Figure 5 is a detail vertical section taken on the line 5-5 of Figure 1.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements the machine ineludes a main axle 1 on which are ground wheels 2, and fixed to and extending rearwardly from the center of the axle 1 is a tongue 3 on the rear portion of which is a tree a which may be of the ordinary four horse type or of any other type compatible with the purpose of my invention. A. steering wheel 5 is arranged at the extreme rear of the longitudinal center of the machine and is carried by a spindle 6, journaled in the rear portion of the tongue 3, and provided with a crank handle 7. At this point I would have distinctly understood that in lieu of the tree 4 and the other means illustrated for hitching the horses to the tongue Serial No. 441,638.

8, any appropriate draft equalizing means may be employed. Manifestly by virtue of the swinging steering wheel 5 the course of the machine may be readily changed when occasion demands. On the front axle 1 are brackets 1 ltnat have to do with the support of the platform organization.

In addition to the elements named the machine includes a reel 15 which has for its function to deflect the upper portions of the grain stalks rearwardly so as to facilitate the cutting of the stalks by the means hereinafter described.

The said reel 15 is mounted in the manner illustrated in vertically adjustable levers 16 in combination with which I employ braces .17 so that the reel may be positioned at various heights, according to the heights of the grain to be harvested and threshed. At

'The fulcrum or pintle 21 of the lever 20 is carried by crossed braces 22 interposed between and fixed to spaced transverse front and rear frame portions 22- of the machine as best shown in Figure 1. Manifestly the braces 22 afford a solid support for the fulcrum or pintle 21 so as to contribute to reliability of operation of the sickle bar of the cutting mechanism 17. The machine also comprises transversely movable endless aprons 23, mounted on outer and inner rollers 24: and 25 and arranged in a horizontal plane slightly above a longitudinally movable endless apron 26 mounted on forward and rear rollers 27 and 28. The aprons 28 are designed to receive the cut grain, and to move the same inwardly and discharge it on the apron 26. The apron 26 is driven by a roller 28 fixed on a transverse shaft 28. The shaft 29 is journaled in bearings 30 arranged at intervals in the Width of the machine, and the inner rollers of the transverse aprons 23 are connected with the said shaft 29 through the medium of the sets of gears 31. It will also be noted by comparison of the figures of the drawings that a driving connection 32 is provided between the shaft 29 and the reel15, and that a driving connection is provided between the shaft 29 and the lever 20, the latter driving connection including an appropriately supported miter gear 33, a miter gear 34 fast on the shaft 29 and intermeshed with the miter gear 33, and a pitman 35 interposed between and connected to wrist pin 36 ofi the center of the gear33 and the rear arm of the lever 20. Manifestly the utilization of the transverse shaft 29 to transmit motion to the sickle bar 17 ofthe-cutting mechanism, the reel, anchthe aprons 523- and 26 is an important feature of my, invention inasmuch as itemtributes to the Simplicity. and durability of the machine and promotes reliability in operation.

Onthe transverse shaft 29 is a sprocket gear 40 and on said sprocket gear 40 is a sprocketbelt 41 that connects the sprocket gear 40 with a sprocket gear 42, fast on a shaft 43. The shaft 43 is clutched at 44, Figure 1, to the shaft 45 of the internal combustion engine 46. It is to be understood in this connection that the clutch is manually controlled so that at any time an attendant may disconnect the shaft 43 from the internal combustion engine. By virtue of this provision it is within the ability of an. attendant of the machine when necessity arises to quickly stop the actuation of the actuating mechanism, the reel, and the aprons described.

The beforementioned shaft 28 on which the roller 28 is fixed, is connected by a crossed belt 29 Figure 1, with the shaft 43 so that the apron 26 will be driven from said shaft 43.

Carried by the main axle 1 are brackets 14 with apertures at intervals in the length thereof. Connected adjustably to the said bracket are thebraces 51 of, the platform 52. At 53 are adjustable braces through the medium of which the short portion of the platform 52 may be tilted upwardly or downwardly as required by the heights of the grain to be harvested. In this connection it will be observed that the braces 53 are connected with a hand adjusting lever 54 that is fulcrumed on the tongue 3 and isequipped with a detent 55 for cooperation with a segmental rack 56, fixed to the tongue 3 Figures ,2 and 4.

The longitudinal apron 26 has for its,

function to feed cut grain to the cylinder 57, best shown in Figure 5 said cylinder 57. being appropriately arranged relatively to a concave or concaves 58. In. this connection I wouldsay that it is within the purview of my invention to construct the cylinder 57 and the concave 58 in any ordinary manner compatible with the purpose of the invention. It is also within the purview of my invention to employ in conjunction with the cylinder and concave, a rotary beater 5 7 a chaifer' .67, a straw rack. 60., the casing 61, the grain auger 62, the fan 66, the tailings auger 63., the grain elevator 64 and the grain auger 65 that extends from theupper end of the elevator 64. The said auger 65 is designed to convey grain to a wagon body 65 that is moved in the relation shown in Figure 1 to the machine while the machine is in operation. The grain. fan. 66" and: the chaffer. 67 mayalsov be of the ave-ll" known construction. in. thrashing. machines or of any other construction. appropriate. to my novel machine.

I, therefore, do not; deem-it necessary to illustrate said fan: and chafferc in. detail;

From the straw rack or racks 60. the threshed straw is delivered to theground,

andfromthisit follows that the straw be easily turned under the. ground toserve.

for fertilizing. purposes. At, thiswpoint I would direct attention to. the fact that all of the working parts of. the. organized thrashing mechanism. and. grain: and I straw delivering. mechanism are actuated. from. the shaft of the internal combustion engine.

46 so that the sole province of the. horses employed. isto move. tl1e...mag hine forward incident to theoperationlof themachine for the. grain. cutting, thrashing. and. 'delivering.

purposes- Manifestly the main frame. of imy novel machine may be of the construction illustrated or of any other. construction compatible. with the purpose of. my invention without affecting the invention asdefined in my appended claims.

In the operation ofv the novel machi-neit will be. understood. that. after the. machine is put in operation all that is necessary for the. attendant. or. a-ttendantsto do is tocontrol the draft animals, and to manipulate.

the steering wheel. 5 wheneverri-t; is necessary tochange the course of thema'chine- It will be apparent. that-my novel; machine rests on the groundsat: three pointsei. e., thetwo main wheels on the main axle. and

the steering wheel. 5-. at the rieanend of'thetongue 3.

The operator ispositioned on. the rearlend of the tongue and straddles.theleveru-ofthe steering wheelv assembly; andv it isv the prov-- ince of. the driver to guide themach-ineandl.
